	 * Generate a random uuid.
	 *
	 * USAGE: Math.uuid(length, radix)
	 *   length - the desired number of characters
	 *   radix  - the number of allowable values for each character.
	 *
	 * EXAMPLES:
	 *   // No arguments  - returns RFC4122, version 4 ID
	 *   >>> Math.uuid()
	 *   "92329D39-6F5C-4520-ABFC-AAB64544E172"
	 *
	 *   // One argument - returns ID of the specified length
	 *   >>> Math.uuid(15)     // 15 character ID (default base=62)
	 *   "VcydxgltxrVZSTV"
	 *
	 *   // Two arguments - returns ID of the specified length, and radix. (Radix must be <= 62)
	 *   >>> Math.uuid(8, 2)  // 8 character ID (base=2)
	 *   "01001010"
	 *   >>> Math.uuid(8, 10) // 8 character ID (base=10)
	 *   "47473046"
	 *   >>> Math.uuid(8, 16) // 8 character ID (base=16)
	 *   "098F4D35"
